Yarn for the Summer Sea Cropped Cardigan
To crochet the Summer Sea Cropped Cardigan I used ZZ Twist from Lion Brand Yarn.
It’s a beautiful yarn with Z-twist, which makes the crochet stitches look more defined.
The Perfect Spring & Summer Crochet Project
The Summer Sea Cropped Cardigan is the perfect crochet cardigan for spring & summer.
It’s made in 5 pieces, which makes it a perfect “grab & go” project, which is really convenient during the season where everyone is typically spending more time outside.
The lace stitches on the cardigan also makes it great for spring and summer, where the thickness of the cardigan isn’t as important.

Crochet Pattern Notes
- This crochet pattern is written in US terms.
- All measurements given are unblocked.
- Note that measurements are given as exact as possible. But crochet tension & technique might give variations in the result, that changes from person to person.
- Read pattern instructions carefully before beginning to make sure you understand everything. It might save you hours frogging your work & crocheting it again!
- Make a swatch that measures at least 10 x 10 cm / 4 x 4 inches using the stitch the gauge is given for. If your swatch matches the gauge, you’re good to go. If the gauge is wrong, you might need to change your hook. Go up in crochet hook size if your stitches are smaller & go down in crochet hook size if your stitches are bigger. Learn more about testing gauge.
- Check yarn info if you want to find an alternative or test your yarn against the gauge. Learn more about substituting yarn.
